IMPROVEMENT IN SIGNAL-LANTERNS.

Specificationnforming part of Letters Patent N0. 222,474, dated December 9, 1879 application filed u October 4, 1879.

To all whom it may concern:

Be it known that I, THOMAS S. EASTER- BROOK, ot' Toledo, in the county of Lucas and State of Ohio, have invented a new and Improved Lantern, of which the following is a specification.

Figure lis an elevation of the lantern. Fig. 2 is a vertical sectional elevation of the same.

`Fig. 3 is a perspective view ot' the lanternglobe. FignlE is a perspective view of the metallic plates of the lantern. `Fig. 5 is a side view of the screw.

Similar letters of reference indicate corresponding parts. .a

The object of this invention is to provide an i improved lantern, especially adapted to railroad purposes.

This invention consists of a lantern-globe having two opposite quarter-sections colored and the two intermediate ones uncolored, which globe is set in a lantern-frame that has attached to it two quarter-section. metallic plates that are set opposite each other, so that by turning the globe the colored sections or a, so that when the said globe Ais placed within' the lantern-frame B the thumb-screw G may be passed through the slot b, that extends through a quarter of the circumference of the cap or top D in the frame B, and be secured by the nut c in the said` notch a. The

cap or top D of the lantern-frame B is hinged at d, and held down by a catch, f, and it may be raised for the removal of the globe A.

The metallic plates E, that cover two opposite quarters of the globe A, are fixed with their lower ends in 'the sockets g, and with their ears h held in the slots of the top D. These plates E may be polished on the inside, to serve as reflectors.

F is the foot of the lantern carrying the lamp Gr.

When one light is shown and it is desired to change to the other, the person carrying the lantern has but to loosen the thumb-screw C and move it around, carrying the globe A with it, to the other extreme of the slot b and secure it there.

At present the railroad conductors, engineers, and brakemeu have a white or uneolored lantern for ordinary use, and a red or colored one for a signal-lantern, both of which are kept constantly lighted at night when they are on the road.

By this improvement but one lantern will be y oil, be effected; and in case of immediate danger the changing ot' the white to the red light can be instantly made with this lantern, and the danger thereby averted, while with the other lanterns in use much time is often lost in going for and bringing the red lantern.

This improvement can, at slight cost, be applied to the lanterns in present use.

Having thus fully described my improvement, I claim as new and desire to secure by Letters Patent- 1. A lantern having a parti-colored globe, adjustable by slot and screw in a frame having two opposite quarter-section plates, E E, as and for the purpose specified.

2. The thumb-Sorenr O, in combination with the globe A and plates E, substantially as shown and described.
